OVERVIEW: Alexis Ohanian does not yet appear to have a formal charitable vehicle, but serves on several boards, including Institute on Higher Awesome Studies (IHAS), which "seeks to increase awesomeness in the world." He's also been an advocate for digital rights and net neutrality.

BACKGROUND: Born in New York, Alexis Ohanian grew up in Baltimore. He graduated from University of Virginia in 2005 and co-founded Reddit, a social news aggregation, web content rating, and discussion website. Ohanian also helped launch travel search site Hipmunk, and is a cofounder of Initialized Capital.

ISSUES:

DIGITAL RIGHTS: Ohanian is involved with Fight for the Future, which advocates "against threats to our basic rights and freedoms on the internet." The organization played a role in the strike against web censorship bills SOPA and PIPA. At one point, Ohanian was set on testifying before Congress against SOPA, and fielded feedback from Reddit users.

OTHER: Ohanian is a co-founder and serves as treasurer of the board of Institute on Higher Awesome Studies (IHAS), which "seeks to increase awesomeness in the world by experimenting with new, community driven ways to incubate, fund, and promote awesome individuals and their projects." IHAS is the parent organization of the Awesome Foundation, which has autonomous chapters in the U.S. and globally that distribute $1,000 microgrants to support worthy projects. Thus far, around $2.4 million has been granted to more than 2400 projects. The foundation has chapters in places like Ann Arbor, Baltimore, Los Angeles, Ottawa, Sydney, and Paris.

Ohanian also sits on the national advisory board of Donorschoose.org, an online charity that makes it "easy for anyone to help a classroom in need." He was also a Kiva Fellow in Armenia in 2010. Ohanian's father's parents were genocide survivors.

LOOKING FORWARD: Only in his 30s, Ohanian has plenty of time to ramp up his philanthropy and establish a formal family foundation. Global development work in Armenia is worth keeping an eye on, as is his work through IHAS. His exact net worth is unknown, but may well grow in the coming years. Finally, his recent enagement to superstar athlete Serena Williams is worth watching. The two may well become a philanthropic power couple.
